There are many brands of automobile painting products on the market. Many people cheat customers with mirror wax, polished glaze and other substances. At the same time, many construction workers don't really do preliminary work such as polishing and car cleaning, but simply use polishing machines to polish and wax, and make demonstrations to deceive customers. The real definition of coating is that silicon, the main component of coating agent, reacts with oxygen in the air on the basis of polishing to form an inorganic glass film on the paint surface. This film can provide efficient protection for paint surface in all directions, and can completely renovate old cars, thus achieving the effects of color renovation, bright paint surface and sealing. As far as I know, TAC in Korea has developed a coating agent. Later, many black-hearted businesses were obviously wax, not deceiving customers in the name of coating agents. It is suggested that the landlord buy a coating agent made of Korean TAC called CLIMAX. I run a car beauty shop with good results and high customer satisfaction. I hope I don't get cheated ~
